vposite sides of the frame.

of apparatus within the spirit and scope of the invention.

As shown, the machine comprises a main frame A on which is mounted an auxiliary frame B which comprises two side pieces, one of which is broken away to show the dough sheeting rollers in transverse section. Between the side pieces of the frame B are a plurality of dough sheeting rolls arranged in pairs, each pair comprising a, flanged roll I and a flangeless roll 2 which are adapted to receive a lump of dough C between them for forming the dough into a sheet D which is curled in a known way by rolls la and 2a into a spiral roll E that is deposited into the molding apparatus constituting the invention and generally designated F. The lump of dough C is fed by a conveyor C- to a dough flattening roll H which cooperates with one roller of the conveyor for preliminarily fiattening the lump before it is fed to the upper pair of sheeting rolls. The sheet of dough D is guided from one pair of sheeting rolls to the next by guide plates 3.

The dough molding apparatus i is mounted on the main frame A and comprises upper and lower supplemental frames formed of side bars d and end bars 4a and side bars 5 and end bars da, respectively, there being two pairs of posts mounted on the side bars fibetween which the upper supplemental frame is vertically movable and tiltable relatively to the lower supplemental frame. A tie rod 'I connects the upper ends of the posts of each pair.

Mounted on and between the upper pair of side bars 5 is an endless fabric belt 8 which passes e over the rollers il that are journaled on shafts Iii in the side barsy one of said shafts being adjustable toward and away from the other by suitable known mechanism II to maintain the desired degree of tension on the belt. Similarly, on and between the lower side bars It is a flexible belt I2 carried by rollers I3 journaled on shafts I4 in the side bars, one of which is adjustable by suitable means which may be identical with the means I I.

The upper bars are so mounted that the lower reach of the upper belt 8 is normally in spaced, opposed relation to the upper reach of the lower belt i2 to form a dough molding space between said reaches; and the upper side bars are adjustable vertically to Vary the distance between said reaches of the belts. As shown, the side bars 5 are channel-shaped and have their channels facing each other as best shown in Figure 5 and two shafts It are journaled in said side bars, the opposite ends of each shaft extending through slots Il in the posts 6 that are disposed at op- Each shaft i6 is provided at each end thereof with a pinion I8 which meshes with a rack I9 secured in a recess 2i) in the corresponding post 5. A cover plate 2l closes each recess 2G and has a slot Z2 through which extends the corresponding shaft I?. A handle 23 is xedly mounted on one end of each shaft It outside the corresponding cover plate 2i, while a similar handle 2li is screw threaded on the opposite end of each shaft. By manipulation of the handles 24 the shafts I5 and the upper side bars can be firmly clamped on the posts 6 in any of differently spaced relations to the lower side bars 4 so as to adjust the space between the juxtaposed reaches of the two belts.

The belts 3 and I2 are driven by any suitable mechanism, but as shown there is a counter-shaft 25 iournaled on the lower side bars 4i of the ceni tra1 frame and connected by a belt and pulley drive 2 5 to a power take-off shaft 2'! of the dough sheeting mechanism which may be driven as usual by an electric motor. The shaft 25 has a chain and sprocket connection 28 with the shaft I4 of one of the rollers I3 of the lower belt, and said shaft has a geared connection 29 with a counter-shaft Si? on which is a sprocket 3| which is connected to a sprocket 32 on the shaft I0 of one of the rollers 9 of the upper plate, by a chain 33 which also passes around chain-tightening sprocket 34. With this construction, the juxtaposed reaches of the two belts will be driven in the same direction as indicated by the arrows and i one of the belts, preferably the top belt, is driven at a higher speed than the other belt. One end of the lower belt 4 extends toward the sheeting and curling mechanism beyond the corresponding end of the upper belt so that the spirally coiled roll of dough E will drop from the curling mechanism onto the lower belt and be rolledy Worked or kneaded between the belts.

To provide firm backings for the juxtaposed reaches of the belts, a metal plate 35 is secured to the lower edges of the upper side bars 5 above the lower reach of the upper belt, and a similar plate 353 is mounted on the lower side bars bars 4 beneath the upper reach of the lower belt and associated with adjustable packing generally designated J which supports a portion of the upper reach of the lower belt through an opening El in the plate 3'5.

As shown, this packing comprises a plurality of packing bars 38 which may be supstantially f identical in construction and each of which comprises a channel having mounting blocks 39 one at each end thereof, one of which is slidable, the blocks having the respective holes lll and 4I each to receive a pin i2 that is carried by a rod 43 mounted to move about its horizontal axis in an actuating arm 4. Some of the arms 44 have hubs 44a rotatable on a shaft 45 whileother arms have hubs 44h keyed on the shafts. Slots 46 are provided in the arms 44 to permit oscillation of the pins 42. Certain of the bars 38 are adjustable independently of the other bars, both laterally of the lower belt and angularly with respect to the plane of the upper reach of the belt. As shown, the packing bars 38 are spaced horizontally and the arms i4 supporting the two outermost bars are slidable but non-rotatable relatively to the two corresponding shafts 45, being keyed on said shafts as indicated at 44e. Said arms may be slid longitudinally of the shafts by any suitable means for varying the spacing of the bars and for changing the angular relation of the bars to each other, but as shown a pull slide 48 is mounted in each post E for each of the corresponding arms and. has ngers i9 disposed at opposite sides of said arm so that by pulling the slide longitudinally of itself, the corresponding end of the packing bar connected to said arm may be swung in a plane approximately parallel to the upper reach of the lower belt.

For swinging the packing bars into relations angularly disposed to the plane of the belt reach, or tilting the bars in vertical planes, each shaft i5 has a handle 5I) rigidly connected to one end thereof and a handled nut y5I screwed on the other end thereof, said handles Sii permitting the shafts to be oscillated to swing the arms 44, and the handled nuts 5I serving to clamp the shafts in adjusted positions.

The hubs 44a of the arms which support the intermediate packing bars are freely rotatable on the. shaftsliv and areractuatedk by vcrank arms 5.2 that are; rigidlyl connected to. operating; shafts journaled inthe side. barsA 4; which crank arms 52` are. connected' by links F14 to pivot lugs 55 on the-hubs- 44a'.. Each shaft 53 has anv operating handle 56 at one end and a handledy nut. 5J at. the other end so .that the shafts may be: rotated by the. handles 5E for swinging-the.- barsin vertical planes and the bars may. be locked in adjusted positionsby. the handled nuts'l.

With this construction, itl will be observed'that the packing .bars 38l maybe disposed in approximately a common flat plane. with the belt reach and in a certain spaced relation as shown in Figure 5, or they outermost-packing bars maybe movedhorizontally relatively to the other vbars and some or all ofthe packingrbarsmay be elevated to change the shape of the dough working surface formed by the belt reach, as shown iin FigureV 6. Also the upper beltvmay bemoved toward and from the lower belt to adjust the size of the-dough working space between the juxtaposed reaches of the two belts, Figure 5 showing onespacing of the belts. and Figure 6 showing a different spacing. These adjustments may be widely varied inzaccordance with the weight and size of the dough roll and the nature of the dough, whether soft or hard, and to obtain a desired distributionof the dough in the roll. As the roll is rmoved by and between the. belts, blunt pointed ends are formed on the roll, the optimum dough texture andv skin is ensured, and .the loaf isv sealed as desired.

In some instances it may be desirable to provide a iiexible metal sheetbetween the packing bars and the belt reach so as to ensure a more uniform support of the belt between the spaced packing bars. Such aconstruction is schematically illustrated in Figure 17 where the sheet metal sheet is designated by the reference character 58 and overlies the opening 3'I`in the plate 36 with one end fastened as by screws or rivets 59 to the plate 36 and the other end loosely lying on the upper surface of said plate.

As above indicated, the apparatus of the invention may be used with varioustypes of sheeting and curling mechanisms and regardless of the direction in Which the roll of dough is spirally rolled. Figures 1l and 12 illustrate the roll of dough E coiled in one direction by the apparatus f shown in Figure 1, while Figures 13 and 13a show a roll L of dough spirally rolled in the opposite direction by a so-called drag curling mechanism which includes a belt 6U which pulls the sheet of dough 6| beneath a flexible fabric or woven metal sheet 52 so as to roll the dough sheet 6l to produce the roll K. The roll of dough K may be fed into the curling mechanism from sheeting rolls like the rolls l 2 hereinbefore described, the drag curling sheet 62 serving in general the same function as the curling rollers I a and 2a'of Figure 1. The dough roll K can be transferred from the curling mechanism 6D-62 to the space between the mounting belts 8 and I2 by any suitable means, for example, by gravity or by manual pushing of the roll on to the belt l2. The belts 8 and l2 are identical with those hereinbefore described and roll, work and knead the dough roll K in the same Way in which said belts act upon the roll E as hereinbefore described.

From the foregoing it will be understood by those skilled in the art that the packing bars 38 may be adjusted into various positions to produce rolls of dough of many different shapes. For example Figure shows one arrangement ofthe packingv bars to produce a so-called French loaf E, While in Figure 16. another-adjustment of the packing bars which may be utilized for producing a` Vienna or pointed loaf rE'.

While We have shown and describedv the invention as embodied in certain structural details, it will be understood that this isl primarily for the purpose of illustrating the ltnrinciplesr ofthe inven tion and that many modifications'and'changes may be made-- in the constructionof the apparatus within the spirit and scope of the invention. For example it will be apparent that the adjustable packing could bemount'edr on the upper plate 35 instead of' on the lower platev 36, and that the belt opposite theone-associatedwith the packing could be eliminated and replaced by a stationary plate. It `will also be apparent that the adjustable` packing could be mounted on both the upper plate 35' and the lower plate 36 so that there is means for adjusting the packing under Y both reaches of the belts.
